Oh no, App Error 523

I've recently changed my firmware to 4.5 and like an **bleep** I tried using a theme that's not supported with the new firmware and got the App Error 523 blues The problem is that my desktop software won't let me erase the theme because it's the current theme for the BB (I'm guessing) and it won't let me do a master reset. I've heard about JL_Cmder but I can't get it downloaded and don't even know if I should use it since this is my work phone. Worse is that since it's my work phone, I have it password protected, I can connect it to the desktop manager just fine and have almost everything backed up already but can't backup again or deleat anything. Any idea how I can get my BB back to normal?

Re: Oh no, App Error 523

Unfortunately doing a battery pull didn't work but hopefully I'll be able to get it working soon, I guess it's because it's the current theme that's keeping it from being able to be reset. I was able to get my Device Manager to recognize it for a while but it won't anymore so I haven't been able to reload 4.5 on it but if I can get it to recognize the device again I'll give it another shot. When I did get the device in the first time though I couldn't get the device manager to reload 4.5 again which has me a little worried. I there was a way to completely reset the device back to factory defaults though it would be a miracle.

After the OS reload the device will have been wiped. In "most" cases after getting a java error the data would has already been erased. So if you follow the other ways to reload the OS in my previous post you'll be good to go.

Ok, so I'm still having trouble and can't get a replacement so I thought I'd try using Jl_Cmder and downloaded the program but I get an error message and the program won't run, I've encluded the error message and the properties window, if anyone can help I'd appreciate it! http://i14.photobucket.com/albums/a311/headexpl0dy/errorJL_Cmder.jpg
